CAT 2000 — DILR Question 29
Answer the following question based on the information given below.
The figures below present annual growth rate, expressed as the % change relative to the previous year, in four sectors of the economy of the Republic of Reposia during the 9 year period from 1990 to 1998. Assume that the index of production for each of the four sectors is set at 100 in 1989. Further, the four sectors manufacturing, mining and quarrying, electricity, and chemicals, respectively, constituted 20%. 15%. 10% and 15% of total industrial production in 1989.
It is known that the index of total industrial production in 1994 was 50 percent more that in 1989. Then, the percentage increase in production between 1989 and 1994 in sectors other than the four listed above is
Answer & solution
- A
57.5
89.5
- C
127.5
- D
47.5
If total industrial production in 1989 is 100, then in 1994 it is 150.
From the previous question,
Contribution of 4 sectors in 1989 = 60
Contribution of 4 sectors in 1994 = 74.2
∴ Contribution from other sectors in 1989 = 100 – 60 = 40
∴ Contribution from other sectors in 1994 = 150 – 74.2 = 75.8
∴ Percentage increase = × 100 = 89.5%
Hence, option (b).
